That's 70 megs, after not being restarted for weeks.

Babeld disables RAs, just like every IPv6 routing protocol.  The simplest
solution is to set up a static IPv6 address on your node before starting
babeld.

(The IPv6 specs are very clear: RAs are sent by routers, and received by
hosts.  Under Linux, enabling forwarding has the side effect of disabling
reception of RAs.  There are very valid reasons why this needs to be done.)
